Today, when synchronizing data, I found that some deleted files were not deleted. Check quickly to find that IO error encountered caused the problem that files cannot be deleted. Search on the Internet and test that it can be used. In general, it is permissions or there may be a problem with the disk.

The server uses the windows version of cwRsync for synchronization. An error occurs when the delete parameter is properly synchronized.

IO error encountered-skipping file deletion

Looking for a long time but did not find a solution, checked the directory permissions, the server log did not see the disk error log information, found a temporary solution on the Internet.

Taking a closer look at the parameters of rsync, it is found that one option is:

-- ignore-errors will be deleted even if there is an Istroke O error.

(delete even if there is an Imax O error)

So add this parameter, perform synchronization again, and the problem is solved.

But as for why rsync misreported this error, I haven't found the reason yet. if anyone knows, you are welcome to answer the question.

The common parameter options of rsync are attached for your reference:

Note:

If you run the rsync command as a normal user, the owner of the synchronized file will be changed to this normal user identity.

If you run the rsync command as a superuser, the owner of the synchronized file will maintain its original user identity.
